\ APPARATUS FOR STORING AND DISPENSING COMBUSTIBLE LIQUIDS.

To all whom it may concern:

Be it known that I, GILBERT H. Poon, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of Wisconsin, have invented new and useful Improvements in Apparatus for Storing and Dispensing Combustible Liquids, of which the following is a specification.

My invention relates to improvements in apparatus for storing and dispensing combustible liquids under hydraulic pressure, and it pertains, among other things, first, to the device for returning the water which has previously been used for elevating the combustible fluid, back to the original water reservoir for repeated use; second, to the device for automatically indicating the quantity of water in the water reservoir, and third, to the device for automatically cutting off the hydraulic pressure from the gasolene tank in case of accidental fire.

My invention is further explained by reference to the accompanaying drawings, in which- Figure 1 represents a vertical section of a portion of a building, showing a side view of the apparatus for elevating gasolene and the like, which apparatus is also shown partly in section, and Fig. 2 represents a vertical section of that portion of the building shown in Fig. 1, drawn at right angles thereto and in which a side view of the apparatus is shown.

Like parts are identified by the same reference numerals throughout both views.

1 represents a gasolene tank which, for safety and convenience, is preferably located below the surface of the ground on the exterior of the building, as shown in Fig. 1.

2 represents a duct through which gasolene may be conducted to the tank 1.

3 represents a manually controlled valve for closing the duct 2.

4 is a water tank which is preferably located on a higher level in the upper portion of the building, and the water tank 4 is connected with the gasolene tank 1 through the duct 5, horizontal branch duct 6, vertical duct 7 and horizontal branch duct 8, which branch duct 8 is connected with the lower side of the tank 1 through the L-shaped bend 9, whereby it is obvious that when the valves are open in sald ducts, the gasolene in the tank 1 will be put under pressure of the waterjrom the tank 4, when, owing to the greater specific gravity of the water, it will Specification of Letters Patent.

remain at'the bottomgof the tank 1 while the gasolene will be forced upwardly thereby, when it will be caused, by such pressure, to pass down through the vertical duct 6, thence through the horizontal duct 7' to the vertical ducts 8 and 9', and from the duct 8 to the duct 10.

It will be understood that when the valve 11' is opened, the gasolene is free to pass down through the duct 9 and from thence to other places of consumption for heating and lighting or other purposes. When, however, the valve 11 is closed, the gasolene will be forced up through the duct 8 and may be drawn therefrom through the outlet duct 12 into a receptacle therefor, as may be found convenient when-selling or otherwise disposing of the same. The passage to the duct 12 is controlled through a valve 13, which valve 13 is opened by pressing downwardly upon the lever 14.

Experience has demonstrated that it is sometimes desirable to exclude the hydraulic pressure from the gasolene, and to accomplish this object I have provided a--valve 15 which controls the passage of water from-the tank 4 to the tank 1, and the valve 15 is controlled by the operating lever 14, the lower end of which lever is connected with the valve15 through the wire 16. The lever 14 is pivotally; supported from the upper end of the duct 8 by the bracket 17 and pivotal bolt 18, while such lever is pivotally connected with the valve 13 through the pivotal bolt 13 and valve rod 14. Thus it will be obvious that when a downward pressure is applied to the'free end of the lever 14, the valves 13 and 15 will be bothsimultaneously opened, whereby the piressure from the water I,

in the tank 4 will be communicated to the gasolene in the tank 1, and the gasolene will be simultaneously forced out through said tank through the ducts 7 and 8 and out-let duct 12. When, howeyer, the pressure on the lever 14 is released, both of said valves Y13 and 15 will be simultaneously closed,

whereby the escape of gasolene will not only be out off, but the pressure of water on the gasolene will be simultaneously stopped. In view, however, of the fact that it is sometimes desirable to retain the gasolene under constant pressure, as is the case when using the same for heating and lighting purposes, I have provided the rod 16, which is slidably and loosely connected with the lower end of the lever 14 through the aperture 15, while it is adapted to be drawn up manually and supported at a higher elevation by engaging the loop'19 connected with the upper end of said rod with one of the hooks 20. It will now be understood that when the loop 19 is caused to engage the upper hook 20, shown in Fig. 1, the valve 15 will be opened independently of the action of the lever ll, whereby the gasolene in the tank 1 will be maintained under pressure of the water from the tank 4. while the valve 13 will remain in its closed position. In view of the fact that in case of accidental fire it is important to automatically prevent the further escape of gasolene and to relieve it of all pressure, I have provided the rod 16 with a fusible link 21 which connects the lower portion of the rod 16 with the upper portion 16, whereby in case of accidental fire, the link 21 will fuse and thus permit the valve 15 to automatically close, whereby the gasolene in the tank 1 will be relieved from further hydraulic pressure. I It will be understood that as gasolene is consumed or otherwise removed from the tank 1, said tank will be filled with water, while the water in the tank -l will be proportionately exhausted when it will become necessary to force the water from the tank 1 backto the tank 4 for repeated use. To accomplish this object, I have provided a suction and force pump 22, which pump is connected with the lower side of the reservoir 1 through the ducts 23 and 8, while the out let of the pump is connected with the tank a through the branch duct 24 and check valve 25 and duct 5.

It will now be understood that when the suction and force pump '22 is operated water will be drawn from the reservoir 1 to said pump and forced therefrom up through the ducts Q4 and 5 back to the reservoir l, when it may be repeatedly used.

25 is an outlet duct through which water and sediment may, if desired, be withdrawn from the system, and the duct :25 is closed by a manually controlled valve 96.

As a convenient means of indicating the quantity of water in the tank l have provided such tank 4 with a float 2i, and the same is guided in its vertical moven'ient by a plurality of vertical rods 28 operating in apertures 29 provided therefor in such float, whereby the float is guided in its vertical movement upwardly and downwardly as the tank 4 is filled and emptied. 'lihe float E2? is connected with index pointers 30 through a flexible cable 31, which cable extends up wardly from said floa thence over the pal-- indicate the height of the water in the tank 4.

As a means of protecting buildings in which my system is installed from the danger of using gasolene and other combustible fluids, the system is preferably inclosed by fire proof-walls 34 and 35, and when thus inclosed, access to the pump and other parts of the system may be reached through the doors 36 which are retained in place in the doorway 37 by retaining flanges 38 or in any equivalent manner.

While I have shown and described a single duct communicating from the water tank both directly with the gasolene tank and indirectly through a pump, whereby a portion. of the same duct may be used for leading water from the water tank to the gasolene tank and from the gasolene tank back to the water tank, it is obvious that two separate ducts may be employed between said tanks, one communicating direct from the water tank l through the vertical duct 5, branch duct (3, vertical duct 7, branch duct 8, and L-shaped bend 9 to the gasolene tank at one side of the pump, and the other duct communicating from the gasolene tank to the water tank through the pump.

lit will be understood that in view of the fact that the rod 16 may be freely drawn through the aperture 15 of said lever as stated the valve 15 may be opened Without moving the lever 14 or opening the valve 13. When, however, the fusible link 21 is melted, said rod 16 is free to drop and pass through the aperture in said operating lever 14, thereby permitting the valve 15 to close without moving said lever 14;.

Having thus described iny invention, what I claim as new, and desire to secure by Letters Patent, is-- ln a device of the described class, the combination. of a water tank, a gasolene tank located on a lower plane than said water tank, a pump. a water duct connecting the bottom of said water tank with the bottom of suit gusolene tank both outside of and through said pump, a valve located in said last named duct, means for manually closing said valve, a check valve for preventing the return of water from said water tank to said pump, means for withdrawing gasolene from said gasolene tank under pressure of the water from said water tank, and means for supplying said tanks respectively with water and gasolene.

in testimony whereof I alfix my signature in the presence of two witnesses.
